galax.function.e_div_v

galax.function.e_div_v(lhs_field, rhs_field, out)

Builtin message function that computes a message on an edge by performing element-wise div between features of edge and destination if the features have the same shape; otherwise, it first broadcasts the features to a new shape and performs the element-wise operation.

Broadcasting follows NumPy semantics. Please see https://docs.scipy.org/doc/numpy/user/basics.broadcasting.html for more details about the NumPy broadcasting semantics.

Parameters

• lhs_field (str) – The feature field of edge.

• rhs_field (str) – The feature field of destination.

• out (str) – The output message field.
